Uppena, now Henchir Chigarnia, about 1/2 way between Sousse and Hammamet. The archaeological site has three baptismal fonts. One is a large stone above-ground vat with an 8-aveola shaped rim and circular lower steps inside. Standing in the bottom, ,the circular area is about two feet in diameter. The next step up is about three feet in diameter. There are two tall steps up to aveola level, which came to my chest. The aveola level is about six feet in diameter.
